Observing Basic Port Information
The basic port information, such as link up, link down, transmit/receive activity, enabled/disabled as well as auto partition can be easily spotted through the Port Indicators located in the first row of the Mini-Console.
Figure 3.3 Port Indicators
Port Indicators: Showing the activity of ports such as link up, link down, Tx/Rx, enabled or disabled.
Link Up Ports Partitioned Port Link Down Ports
Mini Console
3-3
The Port Indicator shows the ports that are linked up by intensifying the light for the ports that are available. The example above, Fig 3.3 shows ports 1~4, are linked up (or available) and port 6 is partitioned.
While the ports are receiving or transmitting data, the port’s number will be flashing.
When a port is disabled by the administrator, an amber frame around the port number will be turned on.
If the outline is blinking, it means it has been partitioned automatically due to some error condition such as a loop or broadcast storm that has been detected.
Port Indicator Definitions
The following table summarizes the definition of the port indicators.
Port Number
Frame Indicates
Slightly on Off Port is available but link is down. On Off Port is available and link is up. Flashing Off Link is up and
transmitting/receiving data. On On The port is link up and disabled by
the administrator. On Blinking The port is link up and partitioned
by machine itself due to errors.

Table 3.2 Menu Tree
Exiting the Menu Tree
To Exit a Sub-Menu cycle through each menu item until a “MAIN MENU” or “BACK” is displayed in the Message Zone. Press <Enter> to return to the Main Menu or previous menu level.
Observing Network Traffic
The network manager may want to see the traffic load for every segment and try to balance the load. It is easy to do so with FSW-0803TX by selecting the UTILIZATION menu. While utilization is displayed in the message zone the level of Utilization for the enabled ports is indicated by the gauge bars moving up and down as the traffic load varies.
The reference for the level of utilization is based on the speed of the port that is running. For example, a port that is running in 10M half duplex, the 100% stands for the bandwidth of 10M. Following table show the relation for each speed:
SPEED 100% Stands for: 10M half duplex 10M 10M full duplex 20M 100M half duplex 100M 100M full duplex 200M
Mini Console
3-8
Observing Collision Level
When Collision is the menu item in the Message Zone, the Port Number will be illuminated for each port that is connected and the Bar Gauge will continuously move up or down indicating the percentage of Collision for these ports. Collision occurs when two or more ports send data to the same port at approximately the same time. The Collision percent can be calculated with the following formula.
Collision Ratio = (number of packets collided / number of packets transmitted) * 100.
Monitoring Ports Status
Users can view the status of all 8 ports simultaneously or individually with the PORT STATUS menu.
Figure 3.4 Port Status
When monitoring individual ports, the status is auto cycled through each setting, the configuration is displayed in the Message Zone and the bar scales under the port number are illuminated.

Optimizing Network Performance
When the network traffic is heavy, overloaded ports can be identified by watching the Utilization or Collision Ratio. It may be the time to tune the system to match the environment.
Since the system resources are shared by all ports, the system allocates a limited budget to every port to prevent one failed port from using up all the resources. However, since the loading varies from port to port, the resources allocated for each port should be changed based on the traffic via the Mini-Console to get the best network performance.
Three resource modes are available, Low, Medium and High.
The following table shows the resource distribution between modes.
MODE Using Condition Low The port assigned the lowest amount of
resources. Medium The port assigned a medium amount of
resources. High The port assigned the highest amount of
resources.
Table 3.6 Resource Mode
Mini Console
3-13
Configuring Ports
All the ports of FSW-0803TX support Auto-Negotiation and the default for all ports are configured in this mode. In the Auto-Negotiation mode, the switch learns the setting of the opposite site and configures itself to meet its counter part.
However, in rare conditions you should configure manually, such as when the opposite site does not support Auto Negotiate.
To configure a port, first select the port and then select the desired setting.
PORT SETTING>PORT (1~8)><setting>
When a setting is selected, an asterisk symbol (‘*’) will be added to the first character of the string. Making it convenient to check what the settings for these ports are, by just going through the sub menu of PORT SETTING, without making any confirmation. When you see an item that begins with an ‘*’, the port is set in that mode.
While AUTO-NEGO is set, the speed and duplex selection are no longer available. The speed and duplex will be decided by the result of the negotiation. By contrast, if either the speed or duplex is selected, the AUTO-NEGO function will not work. It forces the port to run in the mode just set.
All settings will be saved in the EEPROM.
Setting the port speed forces the port to use the selected speed only, if the device being contacted is set at a different speed, the data will not be sent. When the setting is Auto Negotiate, the port will negotiate to the fastest speed available to both ports.
If the port being contacted doesn’t have Auto Negotiate, then this port must be configured to match the port being contacted.

VLANs
FSW-0803TX NWay Switch supports up to 8 virtual LANs (VLANs). VLANs effectively divide the ports into separate domains through software. Ports in one VLAN cannot communicate with ports in another VLAN. To allow ports from different VLANs to communicate, assign them to a common VLAN. You can configure each port to join one VLAN or more than one of the 8 VLANs through the Port Setting menu. The default assigns all ports to all VLANs simultaneously.
To Configure VLANs:
PORT SETTING><select port>VLAN GROUP><VLAN 1~8><press and hold Enter>
An “*” appears before the VLAN # that the port is configured in. To change to a different VLAN, press and hold Enter at the desired VLAN, an “*” appears before the VLAN # and the “*” is removed from the previously configured VLAN.
Selecting a Buffer Mode
Ports on the FSW-0803TX can be individually set to one of three buffer modes, L (low), M (medium) or H (high). However it is important to note that certain ports share the same memory resources and are grouped together. When selecting buffer modes for ports you should consider a group of ports and distribute resources between the ports within that group. If you set the buffer mode the same (for example High) for all the ports in a group, it is the same as setting them all to medium or low and there will be no gain in performance.
Mini Console
3-16
FSW-0803TX Buffer Groups
Table 3.8 shows the ports that are grouped together and share the same resources for model FSW-0803TX. There are 2 groups and the resources between groups, is independent.
1,2,5 and 6 These ports share buffer resources and constitute a group. For a gain in performance you may want to set one port in this group to High, 2 ports to Medium and one port to Low.
3,4,7 and 8 These ports share buffer resources and constitute a group. For a gain in performance you may want to set one port in this group to High, 2 ports to Medium and one port to Low.

Unit Configuration
Broadcast Storm Protection
Some devices in the network may generate broadcast storms, thereby jamming the network with broadcast packets. It may take about 6-7 seconds to detect a broadcast storm.
When the Broadcast Storm Protection is Enabled, the system will monitor the incoming packets to see if that port is enduring a broadcast storm. While Broadcast Storm is detected, the port will be disabled temporarily and the frame around the port number will blink. The message zone will show the message “BRDCST STORM” altering normal display. Every 2 minutes, the port will be released to see if it is still enduring the broadcast storm.
The Broadcast Storm Protection function is disabled when shipped from manufacturer. This function can be enabled through the Mini Console. The command sequence is:
UNIT CONFIG > STORM DET > ENABLE><Enter and hold>
After the command is entered, it will be saved in the EEPROM.
Loop Isolation
Loop Isolation is an important feature of the FSW-0803TX. This condition could exist if two ports are inadvertently connected to each other causing a loop.
The switching device can not sustain a loop because it produces Broadcast Storm thereby jamming the system with looping packets. FSW-0803TX supports isolating the looped ports. If the function is enabled, the device will monitor all ports to see if there are any loops.
Mini Console
3-18
Once a loop is detected (which takes about one second), it will disable that port. The port number frame will blink indicating it has been temporarily isolated. Every 8 minutes, the port will be released to see if it is still looping.
The function of LOOP ISOLATE is disabled at the time it shipped from manufacturer. You have to enable the function through Mini-Console. The command sequence is:
UNIT CONFIG > LOOP ISOLATE > ENABLE><Enter and hold>
After the command is entered, it will be saved in the EEPROM.
Sub-Menu Command To Set Press: Loop Isolation Enable Enter and hold Disable Enter and hold Back Enter
Table 3.9 Loop Isolation
Lock the Console
Setting this option to Enable locks the system settings. If there is no password set, a prompt will request one be entered.
UNIT CONFIG > CONSOLE LOCK> ENABLE><Enter and hold>
If a User’s Password has been set and enabled, the unit does not allow changing system settings, such as port settings and unit configuration, unless the correct password is keyed in thereby unlocking the Mini-Console.
Unlock the Console
Once the console is locked, a password will be asked when the menu item UNIT CONFIG is selected.
Mini Console
3-19
In the password session, a message “* * * *_ _ _ _ PSW” will be shown. You have to key in the correct password to enter the submenu. The regular Password assigned by you and the Back door Password are accepted. The first four asterisks are used for normal password while the others are used for Back door Password. The regular password is assigned by the user and the Back door Password depends on the Key Code. See “Back Door Password” on page 3-20 for more information.
After the password session is passed, you can go to the sub menu of UNIT CONFIG. The lock sign on the Mini-Console is OFF and you are free to configure any settings.
Secure the Switch
Two passwords are provided to protect the device from being accessed anyone other than administrator. Further information regarding Password and Back door Password, please refer to “Unlock the Console” section.
Set Password
You can configure a password by enter a 4 digit password using the numbers from 0~9. The default is “0000”.
To set the password:
<UNIT CONFIG><SET PASSWORD>enter 4 digits.
After SET PASSWORD is selected, four “*’s” are displayed and the first “*” is blinking indicating it is the current digit. Enter a new number using the <Prev> key. Use the<Next> key to move from one digit of the password to the next one. When the 4 password digits have been entered, press <Enter> to complete the password setting. Ensure that you do not loose your password.
Mini Console
3-20
Cancel Password
Enter the command UNIT CONFIG > SET PASSWORD. Entering four blanks will clear the password when the console is unlocked.
In Case You Forget the Password
In case the password is forgotten the back door password can be used.
Back Door Password
The Back Door Password is useful in case you are locked out of the system because you’ve lost the password. The back door password is always enabled and is derived from “Key Code XX” under the main menu item “System Info”. The “XX” is a random number selected by the device every time the system is powered on and the number is incremented by 1 every 2.5 days.
Please call technical support from your supplier to find out your current “XX” mapping to an 8-digit password!
